It is nicknamed 'Jack' as part of the 'Three Towers of Yokohama' legend, which claims that if you visit all three towers in one day, your wishes will come true.
The tower design incorporates a blend of Western architecture with decorative elements reflecting Japanese craftsmanship of the Taisho era.
The original building was designed by Yamada Mamoru, chosen through a national architectural competition.
The structure survived the 1923 Great Kanto Earthquake, though its tower was partially damaged and later restored.
The stained glass windows were largely reconstructed based on original designs after suffering damage in previous historical disasters.
It is part of the 'Minato-no-Mieru-Oka' sightseeing cluster that highlights Yokohama's role in the Meiji and Taisho era modernization.
The Yokohama Port Opening Memorial Hall is a designated Important Cultural Property of Japan that has served as a symbol of Yokohama's international history since its 1917 completion. Built to commemorate the 50th anniversary of the opening of Yokohama Port, the structure features a distinctive clock tower known locally as 'Jack.' The building is constructed of red brick and granite in a neo-Renaissance style with a high-pitched central tower. It currently serves as a functional public meeting space, housing the Naka Ward public hall. The interior includes a large, ornate hall used for lectures, concerts, and community gatherings. Visitors can observe original architectural details, including stained glass windows depicting motifs related to the port's history. It is one of the 'Three Towers of Yokohama,' alongside the King and Queen towers, which form a famous local sightseeing trio.
The street corner opposite the building entrance provides the best vantage point to photograph the tower and the facade simultaneously.
Check the official schedule before visiting, as the facility often closes to the public during private municipal meetings or local elections.
Bring a camera with a wide-angle lens to capture the full height of the 'Jack' tower from the street level.
Combine your visit with a walking tour of the nearby 'Queen' (Yokohama Customs) and 'King' (Kanagawa Prefectural Government) towers.
Do not assume the entire building is open for interior exploration; many rooms are restricted to administrative or event use.
Closed on the fourth Monday of every month and during the New Year holiday period.
Maintain quiet tones inside the facility as it is an active public meeting space; do not disrupt ongoing events or private bookings.
